Abstract: This invention is directed to a camera which has an information setting device including an information setting member rotatable around a display device. The information setting member is provided with a window member which covers the display device and through which the indiciation displayed on the display device can be seen. The display device is supported on a frame which defines a camera body in association with a cover member surrounding the frame, while the information setting device is supported on the cover member. Accordingly, the size of both devices can be made large without necessity of enlarging the camera body in proportion to the size of the devices. Further, both devices can be assembled independently from each other. Namely, the information setting device is mounted on the cover member which is still separated from the frame. Meanwhile, the display device is mounted on the frame. Finally, the cover member with the information setting device and frame with the display device are assembled.

Abstract: A depth-of-field preview apparatus for a single lens reflex camera is provided with a display circuit responsive to a preview display signal generated by a control circuit with at least one of first and second switches being closed. The first switch is closed when an operating member is operated to an operated position and opened when the operating member is released to return to a non-operated position under a spring bias. In response to the closure of the first switch the control circuit generates the preview display signal and an electromagnetic device causes a diaphragm stop-down mechanism to stop-down a diaphragm. When the diaphragm is stopped-down to a preset aperture size, another electromagnetic device stops the diaphragm stop-down mechanism to set the diaphragm to the preset aperture size and at the same time closes the second switch.

Abstract: A camera water-tight housing includes a hollow body member having a rectangular rear access opening delineated by the rear borders of the body member walls and a rectangular transparent lid having grooves formed in its inside face along its long sides. Each groove includes opposing faces, the inside faces being stepped and a resilient packing engages the face stepped portions and is retained therein by the borders of a pressure plate secured to the lid inside face. In the housing closed condition, the wall end borders along the opening long sides engages the lid grooves between the backing and the groove outer faces to compress the packing and effects a water-tight seal. Locking members are provided on the body member end walls and include hook portions for engaging tabs projecting from the lid to lock it in its closed position and cams for engaging the tabs and ejecting the lid when the members are rotated to separate the hook portions from the tabs.

Abstract: A lens cap is formed with not only a lens covering portion for covering the photographic objective lens of a camera, but also with both a portion, such as protection wall for preventing inadvertent operation of the camera shutter release button and a projection for preventing unexpected movement of the operation member of the camera which is adapted for switching the camera from a normal photography condition to a flash photography condition. The lens cap may be further provided with covering portion for covering the camera viewfinder window as well as the range finder window.
